I'm not a doctor, just to let you know, but I get a similar problem with bumps like acne on my temples accompanied by a headache
and sometimes high bloodpressure. When the bumps
go away eventually, and they may take months, they pit and scar. I also have hair extending down from my hairline to the eyebrows over my temples, not bad bad, but getting bad.
I've also had a head injury in 1989, was stabbed in the right temple and got blood poisoning from improper treatment.
